A cannon, in SABRE-invented terminology, is the situation where two routes meet but continue their courses without crossing, like two billiard or snooker balls cannoning off each other.

The A5 and A6 cannoning in 1922

The most famous cannon is probably where the A5 and A6 formerly met in St Albans; although this is no longer the case, the present-day A1081 and A5183 still cannon at this same point. The 5-6 zone boundary still remains in the same place, meaning that it is entirely possible to move directly from zone 4 to zone 6 by crossing the junction diagonally.

Other cannons include the junction of the A127 and A1159 at Southend, while the A1 and A199 do likewise to the east of Edinburgh.
